yeah the back seats are reclineable. on some 300CE's (not mine though) they also had the reclining back seat...

Very cool for that added comfort.

The switch with the exclamation point, is the exclamation point sideways? like an old horn? if so thats the country horn? I think thats what it is called.. the horn tone will be different when you enable or disable it.

In anycase, the 560SEl is a nice car. had one years ago, great driving car and fast.
